About the ingredient
Anastrozole
A selective non-steroidal aromatase inhibitor that blocks the conversion of androgens to estrogens.
Anastrozole is an oral aromatase inhibitor (AI) designed to reduce the body's conversion of testosterone into estradiol (estrogen). By selectively inhibiting the aromatase enzyme, Anastrozole helps maintain optimal testosterone-to-estrogen balance, supporting hormonal stability in men undergoing testosterone replacement therapy (TRT) or other hormone optimization programs.
This medication is commonly prescribed to prevent estrogen-related side effects such as water retention, gynecomastia, and mood fluctuations — while preserving the benefits of testosterone therapy, including increased energy, lean muscle, and improved libido.
Selective aromatase blocker
Anastrozole binds reversibly to the aromatase enzyme, reducing the peripheral conversion of testosterone to estradiol without affecting other steroid pathways.
Estrogen-balanced TRT
Pairs with testosterone therapy to keep estradiol within a healthy range, supporting libido, mood, and body composition.
Flexible micro-dosing
Three tablet strengths allow precise titration based on lab-confirmed estradiol levels.
